Some of the other maps fixed the on/off problem but were so rich that you ended up with a "dead" throttle and the motor "burbling" at all low RPM low THROTTLE settings.If you like I can send you a picture of the "graph" where I listed all the maps I could get my hands on and compared them as to the RPM's they either ADDED TOO, or SUBTRACTED FROM the stock settings. Most of them added TOO MUCH fuel in the lower end and so I only tried one or two of them, I marked the one I used {419-501} and another one that was close to it 419-503 I called SECOND CHOICE at the bottom.</blockquote>
